Sudan's ousted Prime Minister Abdalla Hamdok returned to his home with his wife on Tuesday evening, several sources told news agencies.
A military official told The Associated Press that Hamdok's house in the upscale Kafouri neighborhood of Khartoum was under "heavy security."
Earlier in the day, Sudan's top general, Abdel-Fattah Burhan, had said he was keeping Hamdok at "my home" for the prime minister's own protection.
"Yes, we arrested ministers and politicians, but not all" of them, Burhan said, adding that Hamdok was "in good health" and would "return home when the crisis is over."
US Secretary of State Antony Blinken later spoke with Hamdok. He welcomed the prime minister's release, but reiterated calls for the release of all detained civilian leaders, the State Department said.
Hamdok's office said that the prime minister had been detained as part of the military operation, along with several others.
The office responded to Hamdok's detention in a statement from the Information Ministry, which appealed for the "liberation of everyone" arrested on Monday.
